Genes affected

CNDP2 (HGNC:24437): (carnosine dipeptidase 2) CNDP2, also known as tissue carnosinase and peptidase A (EC 3.4.13.18), is a nonspecific dipeptidase rather than a selective carnosinase (Teufel et al., 2003 [PubMed 12473676]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Nov 13, 2024

The c.98C>T (p.A33V) alteration is located in exon 3 (coding exon 2) of the CNDP2 gene. This alteration results from a C to T substitution at nucleotide position 98, causing the alanine (A) at amino acid position 33 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
